The Construction Master Pro Trig provides construction professionals with complete trig functions to help them quickly and easily solve complex construction-math problems. It saves time, reduces costs and prevents re-work. You can effortlessly work in and convert between feet-inch-fractions and metric units. Instantly calculate complex construction challenges for stair layouts, roofs, framing and much more. Full trig functions with sine, cosine, tangent, arcsine, arccosine and arctangent.

I have been using Calculated Industries calculators for at least 20 years. I bought them for all my employees so they would stop wasting time and be more accurate. I am lost without my Construction Master Pro Trig. A great tool in the office and on the construction site.

I use this for everything from surveying calcs to finish work. If you don't have one you are wasting a lot of time figuring things the hard way.

I was looking into buying a calculator that will quickly and easily help me with calculating stair dimensions and other angular calcs. This product is spot on

Just want to say that I bought a Professional Measure Master II about 27 years ago. I used it for about 10 years and then bought the Construction Master Pro Trig and put my original calculator in a drawer. Well, about 17 years later (recently), I found it in a drawer and the battery still works! I've used it daily for the last few months now and it's still going strong. Unbelievable! Thanks for a great product.

This calculator meets all of our engineering tasks that we perform. Its great only having to have one calculator instead of two to perform all of the functions provided on this one.

The company I work for builds and repairs API Aboveground Storage Tanks. We go around in circles every day all day long! The Trig functions and the conversion functions are fantastic! We have purchased 7 Construction Master Pro Trig calculators for each of our employees and will purchase more as we hire new people!

Some of the functions that were easily accessable on the earlier model are now hard to find,for example the metric conversions.

One of the better calculators I have used. It far more user friendly than the Jobber or a regular calculator.
